@garritfra Hi! Well, it depends on what exactly you expect in terms of "flexibility", but take a look at the free version of Blocksy wordpress.org/themes/blocksy/. Otherwise, the new "block themes" wordpress.org/documentation/ar are pretty flexible. Block themes by Automattic wordpress.org/themes/author/au or Anders Norén wordpress.org/themes/author/an are free/libre, well-conceived and without upselling attempts on every corners.
